This clip is a version of this one but remastered to make it watchable. The video seemed originally captured on a mobile phone camera (hinted from the use of the h263 codec, the low resolution, poor audio and shaky image), thus the need for a clean up.
The following adjustments were made:
Image stabilized. The original was very shaky, which might be understandable when holding a 100 grams gadget pointed in a direction for 2 hours without stationary support.
Image deblocked. The original had large amounts of blocking which had to be removed since this is a lossy transcode (a lossy transfer from one format to another)
Audio levels adjusted. The audio was barely audible to begin with.
Audio noise reduced. The noise floor was rather high compared to the average volume making it very difficult to discern the speech.
Audio low pass filtering applied. The sound appeared rather aliased.
Further enhancements possible but not tried (for those with CPU cycles to burn):
Increase video resolution (information in the frames) using super resolution techniques. Likely very difficult due to the low frame rate coupled with large changes plus absence of image aliasing.
Increase video frame rate using motion vector estimation and interpolate/construct delta frames using those vector values. This might raise the frame rate to at least 23,976 fps (same as feature film).
